The term "and/or" in this article is only an association relationship describing the associated objects, which means that there can be three relationships, for example, A and/or B, which can mean: A alone exists, A and B exist at the same time, exist alone B these three situations. In addition, the character "/" in this text generally indicates that the associated objects before and after are in an "or" relationship.

The Internet of Things device method based on the Restfull architecture is becoming more and more popular. Among them, Rest is the abbreviation of Representational State Transfer. Under this architecture, things (devices) in the physical world are described by means of resources. And use CURDN (Create, Update, Retrieve, Delete, Notification) to manipulate resources.

In the Open Connectivity Foundation (OCF) system, resources can represent logical functional entities of each device, each functional service of the device, and the status of the device. These logical functional entities are determined by the server Open to the client for access and operation, and the client interacts with the server through the resource operation CRUDN. The parameters of OCF resources mainly include URI, resource attributes, resource references and interfaces.

Among them, the introduction of resource parameters is as follows:

URI: Each resource has its own URI, and some resources have predefined URIs. This resource can be obtained by accessing the corresponding URI;

Property (property): Each resource contains properties, which are used to describe the relevant information of the resource;

Resource reference (link): Establish a reference relationship between resources through links;

Interface (interface): The expression of the open resource and the corresponding operation method.

The above-mentioned properties may include common properties. Common attributes include the basic attributes of resources. For example, the common attributes in OCF Core include:

rt: resource type;

if: The interface of the resource, used to determine the operation mode of the resource;

n: the name of the resource;

id: resource identifier.

A combination of one or more resources in a device can provide a capability. For example, a timer resource (timer), when it is used to provide a capability to the outside world, can be considered as a timing service. In the embodiments of the present application, one device can be used to improve the capability of another device. For example, use the capabilities of ND in the Internet of Things system to improve the function of RCD.

FIG. 2 is a schematic flowchart of a service sharing method 200 according to an embodiment of the present application. This method can optionally be applied to the system shown in FIG. 1 and can also be applied to an Internet of Things system, but is not limited to this. The method includes at least part of the following content.

S210. The first device sends a subscription service request, where the subscription service request includes subscription information of the first service, and the first service is in the set of discoverable services.

S220. The first device receives a response message, where the response message includes content of the first service.

Optionally, the subscription information of the first service may include a subscription identifier, subscription content, and so on.

Among them, the subscription identifier may indicate the type of local subscription service. For example, if the subscription identifier is 0, it means that a resource in a certain service in the second device needs to be subscribed. If the resource of the service in the second device changes, the first device is notified. For another example, the subscription identifier being 1 indicates that the resource is unsubscribed, and if the resource of the service in the second device changes, the first device will not be notified. For another example, the subscription identifier 2 indicates the function of the subscription service, and a second service similar to the subscribed first service is generated on the first device, so that other devices can use the second service on the first device to implement the corresponding function.

The subscription content may include some basic information of the subscribed first service, such as the service identifier, name, address, and so on.

Optionally, in this embodiment of the present application, the method further includes: the first device sends a discovery service request; the first device receives a discovery service response, and the discovery service response includes a set of services that the second device can provide externally .

In one manner, the first device may send a service discovery request to the second device, and obtain the set of services that the second device can provide externally from the set of discoverable services of the second device included in the received service discovery response.

In another manner, the first device may send a discovery service request to the cloud platform, and from the set of discoverable services of the cloud platform included in the received service discovery response, the set of discoverable services of the cloud platform may include one or more A collection of services that the second device can provide externally.

Optionally, in this embodiment of the present application, the first service is in the discoverable service set of the second device, and the discoverable service set of the second device includes a set of services that the second device can provide externally. A collection of discoverable resources can be included in the device. The set of discoverable resources may include a set of discoverable services. Publishing a resource in the discoverable resource collection allows other devices to discover the resource and then access the resource (for example, by accessing the resource to implement a switch operation). A service is published to a set of discoverable services, so that other devices can discover this service, and then use this service (for example, using a timing service).

For example, the first device is RCD, and the second device is ND. ND can put the service link that it can provide externally into the discoverable service collection such as oic.r.service resource, and then ND publishes the oic.r.service resource to the discoverable resource collection such as /res resource; /res resource is The collection of resources that the ND can provide externally. A resource published in the /res resource can enable other devices to discover this resource and then access this resource. The ND publishes the oic.r.service resource to the /res resource, so that other devices can discover the services that this ND can provide to the outside world. In this way, the RCD can discover the services that the ND can provide to the outside world. For example, the services that ND can provide externally include timing, temperature measurement, and camera. If the RCD wants to obtain the temperature measurement service, it can send a subscription service request for subscribing to the temperature measurement service to the ND. The subscription service request includes the subscription information of the temperature measurement service. After receiving the subscription service request, the ND can authenticate the RCD. After the authentication is passed, the content of the temperature measurement service (for example, the current room temperature is 30°C) is sent to the RCD through a response message.

Optionally, in the embodiment of the present application, the first service is in a set of discoverable services of a cloud platform, and the set of discoverable services of the cloud platform includes the services that the second device publishes on the cloud platform and can provide externally. Collection of services.

For example, the first device is RCD, and the second device is ND. ND can put the service links that it can provide externally into its own discoverable service collection oic.r.service resource, and then ND publishes oic.r.service resource to /res resource; /res resource means that ND can externally The collection of resources provided. And ND can publish the oic.r.service resource to the discoverable resource collection/res resource of the cloud platform. The /res resource of the cloud platform may include one or more sets of services that the ND can provide externally. In this way, RCD can discover the services that one or more NDs can provide externally on the cloud platform. For example, the /res resource of the cloud platform includes services that a certain ND can provide externally, including timing, temperature measurement, and camera. If the RCD wants to obtain the temperature measurement service, it can send a subscription service request for subscribing to the temperature measurement service to the cloud platform, and the subscription service request includes the subscription information of the temperature measurement service. After the cloud platform receives the subscription service request, it can authenticate the RCD. After the authentication is passed, the content of the temperature measurement service is sent to the RCD through a response message.

Optionally, in the embodiment of the present application, the method further includes: the first device generates a second service on the first device based on the response message, and the second service includes the same resources as the first service.

For example, after receiving the response message from the ND, the RCD may locally generate a second service that is the same as the resources included in the first service. Each service can include a list of general parameters href, if, it, etc., as well as a list of function parameters. The response message may include a list of function parameters provided by the first service. For example, the first service includes a timing service, and the list of function parameters includes {starttime, stoptime, repeat}. The function parameter list of the second service generated locally by RCD also includes {starttime, stoptime, repeat}.

Optionally, in the embodiment of the present application, the method further includes: the first device publishes the second service to the discoverable resource set of the first device.

For example, after the RCD generates the second service locally, it can publish the second service to its own discoverable resource collection, such as the /res resource. In this way, other devices can also discover the set of resources that the RCD can provide externally. Compared with the resources that the RCD can provide originally, the set has more resources for the second service, such as timing, temperature measurement, and so on.

Optionally, in this embodiment of the present application, the second service includes a subscription parameter, and the subscription parameter is used to identify that the second service is a subscription service. In the first device, subscription parameters can be added to services subscribed from other devices to identify that these services are subscribed, which is different from the services that the first device itself can provide. The subscription parameter may be a newly-added parameter, and the newly-added subscription parameter may be used to indicate the location of the service on the ND.

Optionally, in this embodiment of the present application, the subscription parameter is an anchor parameter.

Optionally, in this embodiment of the present application, the anchor point parameter is also used to indicate the location of the first service on the second device or cloud platform.

Optionally, in this embodiment of the present application, the method further includes: the first device receives first operation information from a third device or a cloud platform, the first operation information includes the content to be modified of the second service; The first device sends a modification request to the second device based on the content to be modified of the second service, and the modification request includes the content to be modified of the first service.

Specifically, the discoverable resource set of the first device, for example, the /res resource, may include resources of services that can be provided by itself and resources of services that can be provided through subscription. If the third device finds that the first device's discoverable resource set contains the content it needs, it can send an access request for query, modification, and other operations to the first device. It is assumed that the first operation information included in the access request sent by the third device to the first device is "write" operation information, which is used to modify the second service. The second service is a service subscribed by the first device from the second device. And, the second service is generated according to the first service of the second device. In this case, after receiving the "write" operation that needs to modify the second service, the first device sends a modification request for modifying the first service to the second device. The second device modifies the content of the first service according to the modification request.

For example, desk lamp 1 (first device) is RCD, and TV (second device) is ND. The desk lamp uses the time service A of the TV to generate the time service B locally. Lamp 2 (the third device) wants to use the timer service B of Lamp 1, for example, wants to set an alarm clock at 7 o'clock in the morning. The first operation information sent by the table lamp 2 to the table lamp 1 includes setting the alarm time of the timer service B to 7:00 AM. The modification request sent by the desk lamp 1 to the TV includes the alarm time of the timer service A set to 7:00 AM. Waiting until 7 o'clock in the morning, the timer service A in the TV can send a reminder that the time has reached the lamp 1 and the lamp 1 can forward the reminder to the lamp 2.

Optionally, in the embodiment of the present application, the method further includes: the first device receives the modification result of the first service returned by the second device; The third device or the cloud platform sends the modification result of the second service.

Specifically, if the second device successfully modifies the first service, for example, the write succeeds, the modification result returned to the first device may carry a success flag, otherwise, it may carry a failure flag or not return the modification result. After receiving the modification result of the first service, the first device may return the modification result of the second service corresponding to the first service to the third device or the cloud platform that initiated the first operation information.

Optionally, in an embodiment of the present application, the method further includes: the first device receives second operation information from a third device, and the second operation information is used to request a second service; the first device is based on the The second operation information sends the second service to the third device.

Specifically, it is assumed that the second operation information included in the access request sent by the third device to the first device is "read" operation information. For example, the second service is a temperature measurement service. After the first device receives the "read" operation information from the third device, the first device can read the current temperature from its own temperature measurement service, and then send the read temperature Give the third device.

Optionally, in the embodiment of the present application, the method further includes: the first device synchronizing the second service based on the change of the first service in the second device.

Optionally, in this embodiment of the present application, the synchronization method includes: the first device receives a notification message from the second device or the cloud platform, and the notification message includes the information of the first service that has changed in the second device. Content; the first device updates the content of the second service based on the content of the changed first service.

Specifically, if the content of a subscribed first service in the second device changes, the changed content can be notified to the first device through a notification message, or the notification message can be sent to the cloud platform first, and the cloud platform forwards it Give the first device. In this way, the content of the same service of the first device and the second device can be synchronized. Further, the content of the same service of the first device, the second device, and the cloud platform can be synchronized.

For example, for the temperature measurement service in the second device, the room temperature measured last time was 31°C, and the room temperature measured this time was 30°C. The second device may send a notification message to the first device to inform the first device that the measurement result of the temperature measurement service has become 30°C. The first device can change the room temperature from 31°C to 30°C in the temperature measurement service subscribed to.

For example, for the timing service in the second device, the timing start time is 7:00AM and the end time is 7:10AM. At 7:00 AM, the second device may send a notification message to the first device to inform the first device of the timing start of the timing service. The first device can modify the status in the timed service subscribed to by the first device to timed start. At 7:10 AM, the second device may send a notification message to the first device to inform the first device that the timing of the timing service is over. The first device can modify the status of the timed service subscribed to by the first device to timed end.

Optionally, in this embodiment of the present application, the method further includes: the first device sends the notification message to the third device.

Specifically, if the third device requests to use a certain subscription service of the first device. After receiving the notification message of the content change of the subscription service, the first device may send the notification message to the third device. For example, according to the notification of the second device, the first device changes the room temperature of 31°C in the temperature measurement service subscribed to 30°C, and then forwards the notification message to the third device to inform the first device that the measurement result of the temperature measurement service becomes Up to 30°C.

S51. The device (ND) that can provide services to the outside world publishes the services that it can provide to the outside world (it can also be considered as the ability of the device to provide to the outside world). ND can provide services externally can include different resources. A service can include one or more resources. When the ND needs to open its services to the outside world, it can put the service links that it needs to open into a set of discoverable services, such as oic.r.service type resources (abbreviated as oic.r.service resources). Each device may have an oic.r.service resource, which can represent a collection of services that the device can provide to the outside world.

An example of an oic.r.service resource is as follows:

In addition, ND needs to publish resources of type oic.r.service to discoverable resource collections such as /res resources. All resources on the ND that can be discovered by other devices can be published to the /res resource. Other devices can obtain resources of the oic.r.service type by viewing the /res resource of the ND, and then discover the services published by the ND in the resource.

S52. Through the discovery process, the RCD can discover the resources and services that the ND can discover by other devices under the /res resource of the ND, and the /res resource includes the resources/sevice that it publishes to provide external services. The discovery process may include: the RCD sends a service discovery request to the ND to discover the set of services that the ND can provide externally. The ND returns a discovery service response to the RCD, and the RCD obtains the set of services that the ND can provide externally from the response.

S53. The RCD selects one or several services (services provided externally by the ND) from the service set obtained in step S52, and completes the registration of the selected service. The registration process can include: RCD sends a subscription service request to ND's resource /oic/service, which provides external services. An example is as follows:

The subscription identifier is 0, which can indicate that the resource in a certain service in the ND needs to be subscribed. If the resource of the service in the ND changes, the RCD is notified. For another example, if the subscription identifier is 1, it means that the resource is unsubscribed. If there is a change in the resource of the service in the ND, the RCD will not be notified. For another example, the subscription identifier 2 indicates the function of the subscription service, and a second service similar to the subscribed first service is generated on the RCD, so that other devices can use the second service on the RCD to implement the corresponding function.

For example, in the subscription service request, the subscription identifier obs (value 2) and the content of the subscription (content included in the links parameter) are included. After receiving the above subscription service request, the ND authenticates whether the RCD is eligible to subscribe to the above service. If so, perform service registration on the ND, generate a management table of the subscribed service and the subscriber, perform the registration service completion response, and return a subscription response message to the RCD. The management table of the subscribed service and the subscriber can include multiple forms, which can be different according to specific implementations. The management table can be used to complete the management and matching of the subscribed service and the subscriber.

In addition, the subscription response message can contain the basic content of the subscribed service. Examples of the subscribed timed service are as follows:

The response message can carry a list of function parameters provided by the subscribed service, such as the above {starttime, stoptime, repeat}. The service or the resources in the service can include a list of general parameters such as {href, if, it}, etc., and can also include a list of function parameters. The function parameter list of each service or resource in the service can be different, and is used to represent the capability of the service or resource.

S54. After receiving the response message, the RCD may locally generate a corresponding second service according to the subscribed first service. For example, the second service can be an image of the subscribed first service or create a copy of the subscribed service. In addition, the RCD can publish the second service as a discoverable service to its /res resource. Each device can have a unique /res resource. In the generated second service, it can be identified as a subscribed service. There can be multiple identification methods, examples are as follows:

(1) Add a parameter in generating the second service to identify that it is a subscription service, and identify the position of the second service on the ND in the anchor parameter. The anchor parameter can identify the real location of the resource (for example, on which device), because generally href only points to a relative position (for example, a specific address on the device); in this way, the network side can accurately locate a certain resource through anchor+href The address of a resource of the service.

(2) Directly identify the position of the second service on the ND in the anchor parameter.

S55. The RCD can register the service information with the ND. After the ND completes the service information registration, it will return a service information registration response to the RCD to inform the RCD whether the registration is successful. After the registration is successful, RCD publishes its subscribed service in its own /res resource, and then other devices may discover the RCD service and can operate the service.

If another device, such as a third party, initiates an access request to the service, after the RCD receives the above access request, it may perform different processing depending on the type of access request. Examples are as follows:

(1) If it is a "read" operation, the RCD can directly obtain the content of the service from the locally subscribed service and return it to the third party.

(2) If it is a "write" operation, after the RCD saves the modified content of the service locally, it needs to send the modified content to the ND. The ND saves the above-mentioned modified content in the resource of its corresponding service. What needs to be explained here is that the service published on the ND can maintain a corresponding subscription service example for each subscription service party (RCD), and use the management table generated in step S53 to manage it.

S56. If the resources in the subscribed service change, the ND may return a service activation response to the RCD, and the service activation response may be in the form of a notification message. For example, when the resource of the subscribed service on the ND changes, the RCD will be notified through a notification message, so as to ensure the consistency of the subscribed service on the ND and the service generated on the RCD.

After the RCD subscribes to the service, it can provide additional services that it does not have. Therefore, TCD can provide richer services with the help of ND.

For example, the desk lamp does not have the function of timing due to the limitation of hardware conditions, nor can it complete the function of timing switch of the desk lamp. However, there is a television device that can provide a timer in the same network. In this way, the desk lamp can subscribe to the timing service resources of the TV and generate a copy locally, which can be discovered by a third party. In this way, because the desk lamp has a timed service, it can provide the function of a timed switch to the outside. When a third party sets a timing time, although there is also a timing service on the desk lamp, it actually completes the actual "timing" task on the TV. When the "timing" task is completed on the TV, the copy of the timing service on the RCD can be synchronized by notification, and the RCD can complete various services related to the corresponding timing service.

Example 2

The above example 1 can be applied to local sharing services, and example 2 can be applied to remote sharing services.

FIG. 6 is a schematic diagram of an application example of the service sharing method according to an embodiment of the application. In this example, a cloud platform is added. The method can include the following steps:

S61. The device (ND) that can provide services to the outside world publishes the services that it can provide to the outside world (it can also be considered as the ability of the device to provide to the outside world). ND can provide services externally can include different resources; a service can include one or more resources. When ND needs to open its service to the outside world, it can put the service link that it needs to open into the resource of type oic.r.service (referred to as oic.r.service resource). Each device may have an oic.r.service resource, which can represent a collection of services that the device can provide to the outside world. For an example of oic.r.service resource, refer to Example 1 above.

In addition, the ND needs to publish its own discoverable service collection, such as oic.r.service type resources, to the discoverable resource collection/res resource of the cloud platform. All resources and services that can be discovered by other devices on the ND can be published in the /res resource. Other devices can obtain resources of the oic.r.service type by viewing the /res resource of the ND, and then discover the services published by the ND in the resource.

Unlike Example 1, RCD may not know which ND device provides the service, but knows the service provided by the cloud platform. For example, RCD regards the services published by the cloud platform that can be discovered by other devices as the services opened by the cloud platform, and it is not necessary to determine the service of that device.

S62. Through the discovery process, the RCD can discover the services that can be discovered by other devices on the cloud platform under the /res resource of the cloud platform, including the resources/sevices that it publishes to provide external services. This may include services that one or more NDs can provide externally. The discovery process may include: the RCD sends a service discovery request to the cloud platform to discover a set of services that can be provided externally by one or more NDs in the cloud platform. The cloud platform returns a discovery service response to the RCD, and the RCD obtains the set of services that the cloud platform can provide externally.

S63. The RCD selects one or several services (services provided by one or more NDs) from the service set obtained in step S62, and completes the registration of the selected service. The registration process can include: RCD sends a subscription service request to /myservice of the cloud platform, an example is as follows:

The subscription identifier is 0, which can indicate that the resource in a certain service in the ND needs to be subscribed. If the resource of the service in the ND changes, the RCD is notified through the cloud platform. For another example, if the subscription identifier is 1, it means that the resource is unsubscribed. If there is a change in the resource of the service in the ND, the RCD will not be notified through the cloud platform. For another example, the subscription identifier 2 indicates the function of the subscription service, and a second service similar to the subscribed first service is generated on the RCD, so that other devices can use the second service on the RCD to implement the corresponding function.

For example, the subscription service request will include the subscription identifier obs (the value is 2), and the content of the subscription (the content contained in the links parameter). After the cloud platform receives the above subscription service request, it forwards the above subscription service request to the ND. It can also be forwarded after the cloud platform authentication or authenticated in the ND. The ND generates a management table of the subscribed service and the subscriber and returns a subscription response message to the cloud platform device, and the cloud platform may return the subscription response message to the RCD. The management table of the subscribed service and the subscriber can include multiple forms, which can be different according to specific implementations. The management table can be used to complete the management and matching of the subscribed service and the subscriber.

In addition, the subscription response message may include the basic content of the subscription service. For an example of the subscribed timing service, please refer to the above example 1.

S64. After receiving the response message, the RCD may locally generate a corresponding second service according to the subscribed first service. For example, the second service can be an image of the subscribed first service or create a copy of the subscribed service. In addition, the RCD can publish the second service as a discoverable service to its /res resource. In the generated second service, it can be identified as a subscribed service. There can be multiple identification methods, please refer to the related description of Example 1 above.

S65. The RCD can register service information with the ND through the cloud platform. After the ND completes the service information registration, it can return a service information registration response to the RCD through the cloud platform to inform the RCD whether the registration is successful. After the registration is successful, RCD publishes its subscribed service in its own /res resource, and then other devices may discover the RCD service and can operate the service.

(2) If it is a "write" operation, after the RCD saves the modified content of the service locally, the modified content needs to be sent to the cloud platform, and then the cloud platform sends the modified content to the ND. The ND saves the above-mentioned modified content in the resource of its corresponding service. It should be noted here that the service published on the ND device can maintain a corresponding subscription service example for each subscription service party (RCD), and use the management table generated in step S63 to manage it.

S66. If the resources in the subscribed service change, the ND may return a service activation response to the RCD through the cloud platform, and the service activation response may be in the form of a notification message. For example, when the resources of the subscribed service on the ND change, the RCD will be notified through a notification message, so as to ensure the consistency of the subscribed service on the ND and the service generated on the RCD, and to ensure that the service published by the ND on the cloud platform is consistent with Consistency of services on ND.

Through the embodiments of the present application, a resource-constrained device can use services shared by other devices in the network to solve the problem of its own lack of function caused by limited hardware resources. Service sharing can also improve the integration of services between different devices, which can provide richer scenario realization capabilities.
